question 23 of 45
how did advancements in technology differentiate world war ii from world war i?
a. the development of long - range weapons reduced the number of overall casualties.
b. powerful tanks and aerial bombings made trench warfare obsolete.
c. the use of large battleships to transport and deploy troops replaced aerial attacks.
d. the introduction of chemical weapons changed the nature of combat.

Explanation:

• Option A: Long - range weapons in World War II (such as long - range bombers) actually increased the number of casualties due to their ability to target civilian populations and large military installations over vast areas. So this option is incorrect.
• Option B: In World War I, trench warfare was a dominant feature. But in World War II, powerful tanks (e.g., German Panzer tanks) and aerial bombings (e.g., the Blitzkrieg strategy which combined tank and air power) made the static trench warfare of World War I obsolete.
• Option C: In World War II, aerial attacks became more prominent with the development of better aircraft for bombing and air - to - air combat. Battleships were still used but not to replace aerial attacks. So this option is incorrect.
• Option D: Chemical weapons were mainly used in World War I (e.g., chlorine gas, mustard gas). Their use was more restricted in World War II. So this option is incorrect.

Answer:

B. Powerful tanks and aerial bombings made trench warfare obsolete.
